There is just one little problem. The nose piece and the side pieces
are attached to the lenses with tiny bolts with a tiny nut on the
inside. Over time (few months), these work loose. If I catch them soon
enough, I can tighten them and they will stay put for another few
months. If I am too slow, the glasses fall apart.

The ones for the nose piece are much more likely to loosen, probably
because they get wiggled more.

I have tried superglue, but it really doesn't hold.

Can anyone recommend a way to secure these nuts? If it is permament,
so much the better. I don't know why they don't use rivets. I will
never want to loosen these nuts.

Careful use of an automatic center punch
could stake the ends of the screws as
they come out of the nuts expanding them
enough to keep them tight. You may be able
to find a small automatic center punch at
your local Lowe's Depot store. After you
obtain one, you may ask yourself "Why did
I never get one of these incredibly useful
gadgets before now?" I have several different
sizes of the things.

Are they all pretty much the same?

Do I need a small one and a larger one? As long as I am justifying
tools to the bean counter...

Those are all the mid sized tools. I have
that size, bigger and smaller. The small
pocket sized punch is probably more what
you would use on tiny screws. I just used
mine on some #4 machine screws to stake
them.

You can grind or file the point to make it
sharper for fine work. I use my punches as
screw starters in wood too. When I hang a
shelf or piece of equipment on a backboard
and want it to be straight and level, I mark
the mounting points then use the punch to
make a hole in the center of my pencil mark
so the screw doesn't wander off to points
unknown.

Try loctite--will secure it and easy to break the bond if you want to remove
the screw.

I just got the GT-ACP you suggested. Cool little tool. I never knew it
existed. Thanks for the tip. It will come in handy. (You can never
have too many tools.)

However, when I tried it on the glasses, I couldn't keep it on thje
end of the little bolt. It looks like it has a rounded end. I almost
punched a hole in the glasses. Maybe someone with better coordination
and better eyesight could make it work.

I think the Loctite will do the job, but I am very glad to have this
little tools.

Thanks

A little bit of paint on the threads should do it - primer even better.

It works, but not nearly as well as Loctite, which was specifically designed
for exactly the purpose you want: to prevent screws from working loose. Nail
polish dries hard and brittle, and will eventually crack and fall away,
allowing the screws to loosen. Loctite will remain slightly flexible for
years. It's five bucks at an auto parts store. One drop per screw is all you
need.

For an eyeglass screw, make that about 1/20 of a drop!

True, true. Best way to apply it is probably to put a drop on a piece of
paper, then use the point of a toothpick to apply a tiny bit to the screw.

Yes it works like just like small screw Loctite except you don't have
to run to the hardware store and spend any money It is best to clean
and dry the screw and nut with alcohol before assembly.

Hold on there, pardner. It ain't a DIY project without at least two
(2) trips to the hardware store. ;-)

Heck, I was just gonna squirt the Loctite right in there without even
taking the nut off. (Unless the instructions say otherwise and my wife
is helping/watching.) I always drop those little buggers on the carpet
or lawn and can never find them.

I you plan on the above then you want to use a wicking Loctite.
It uses capillary action to enter the joint.

If you open up a piece of cheap consumer electronic
gear like a battery operated AM/FM radio you will
often see a red varnish painted on all of the tiny
screws and nuts that hold things together.

On my eye glasses, I pulled the screws out, and dabbed clear nail polish
into the hole. Right before bed, so I wouldn't have nail polish vapor near
my eyes. So far, they havn't loosened up. I can't remember how long ago was
that. But it was some time after the Truman administration. Might have been
after Clinton adminstration, too.

Loctite is the solution. I've heard - but don't know - that it can eat
plastic. When I use it for plastic eye glasses I wrap the lenses in
saran wrap or scotch tape until the job is done.

Green LockTite. It is permanent (like the red) but it also is
penetrating. So you can use apply it after assembling -- probably with
a toothpick in this case.

That's 2 recommendations for green and one for blue. The Loctite site
has this information about the three colors of "threadlockers": green,
red, and blue:

Green: For smaller fasteners. Doesn't say anything about being
penetrating or permanent.
http://www.loctiteproducts.com/produ...id=48&plid=695

Red: For larger fasteners. Seems to be more permanent. Requires heat
and hand tools to remove.
http://www.loctiteproducts.com/produ...id=48&plid=154

Blue: For medium-size fasteners. Appears to be less permanent.
http://www.loctiteproducts.com/produ...id=48&plid=153

None of them say anything about being penetrating.

The green seems harder to find. So far, one hardware store and one
auto-supply store had only the red and the blue. I finally found it at
a Napa store, but it's 10 miles away.



So, I went to Amazon. They have all three and better descriptions:

Green:
http://www.amazon.com/Loctite-Thread...7198 6&sr=8-1

Loctite 290 Green threadlocker is a low viscosity threadlocking liquid
that wicks along the threadsof pre-assembled fasteners to secure them
in place. Since it is applied after assembly preventive maintenance
procedures are simplified. Ideal for fasteners ranging from #2 to 1/2"
(2.2 to 12mm) in size. Localized heating and hand tools needed for
disassembly. Suggested applications: Bolts on alternators air
conditioning belts and distributor clamps carburetor adjustment screws
and hairline cracks.

It's bit unsettling that the photo is of a *red* package ;-)

Red:
http://www.amazon.com/Loctite-Thread...72297&sr= 8-1

Loctite 272 Red withstands temperatures to 450 Degrees F. This
high-temp/High-strength threadlocker is formulated for heavy-duty
applications. Prevents bolts up to 1-1/2" (36mm) from loosening due to
shock severe vibration and heatstress. An exclusive formulation for
newer engines and high performance applications where extreme
temperature resistance is required. removable with heat and hand
tools. Suggested applications: Camshaft sprocket bolts crankshaft
bolts idler bearings press fit filler tubes transmission input and
output shaft threads ring gear and shock bolts.

Blue:
http://www.amazon.com/Henkel-Loctite...9872406&sr=8-1

Loctite Threadlocker Blue 242 locks threaded metal fasteners against
loosening from machine vibration. It prevents leaks and rusting of
metal threads for 1/4- to 3/4-inch (6 mm to 20 mm) nuts and bolts.
Metal parts can be removed with hand tools for easy disassembly if
necessary. Sets in 20 minutes and cures in 24 hours. Especially useful
for small motors, mowers and many types of power equipment.


It looks like green is the one for this job. Thanks.

OK so change mine to the green.
The blue should still work though, just may need to loosen the screw a bit,
apply the blue locktite, then tighten.

Green LockTite. It is permanent (like the red) but it also is
penetrating. So you can use apply it after assembling -- probably with
a toothpick in this case.

That's 2 recommendations for green and one for blue. The Loctite site
has this information about the three colors of "threadlockers": green,
red, and blue:

Green: For smaller fasteners. Doesn't say anything about being
penetrating or permanent.
http://www.loctiteproducts.com/produ...id=48&plid=695

Red: For larger fasteners. Seems to be more permanent. Requires heat
and hand tools to remove.
http://www.loctiteproducts.com/produ...id=48&plid=154

Blue: For medium-size fasteners. Appears to be less permanent.
http://www.loctiteproducts.com/produ...id=48&plid=153

None of them say anything about being penetrating.

The green seems harder to find. So far, one hardware store and one
auto-supply store had only the red and the blue. I finally found it at
a Napa store, but it's 10 miles away.



So, I went to Amazon. They have all three and better descriptions:

Green:
http://www.amazon.com/Loctite-Thread...7198 6&sr=8-1

Loctite 290 Green threadlocker is a low viscosity threadlocking liquid
that wicks along the threadsof pre-assembled fasteners to secure them
in place. Since it is applied after assembly preventive maintenance
procedures are simplified. Ideal for fasteners ranging from #2 to 1/2"
(2.2 to 12mm) in size. Localized heating and hand tools needed for
disassembly. Suggested applications: Bolts on alternators air
conditioning belts and distributor clamps carburetor adjustment screws
and hairline cracks.

It's bit unsettling that the photo is of a *red* package ;-)

Red:
http://www.amazon.com/Loctite-Thread...72297&sr= 8-1

Loctite 272 Red withstands temperatures to 450 Degrees F. This
high-temp/High-strength threadlocker is formulated for heavy-duty
applications. Prevents bolts up to 1-1/2" (36mm) from loosening due to
shock severe vibration and heatstress. An exclusive formulation for
newer engines and high performance applications where extreme
temperature resistance is required. removable with heat and hand
tools. Suggested applications: Camshaft sprocket bolts crankshaft
bolts idler bearings press fit filler tubes transmission input and
output shaft threads ring gear and shock bolts.

Blue:
http://www.amazon.com/Henkel-Loctite...9872406&sr=8-1

Loctite Threadlocker Blue 242 locks threaded metal fasteners against
loosening from machine vibration. It prevents leaks and rusting of
metal threads for 1/4- to 3/4-inch (6 mm to 20 mm) nuts and bolts.
Metal parts can be removed with hand tools for easy disassembly if
necessary. Sets in 20 minutes and cures in 24 hours. Especially useful
for small motors, mowers and many types of power equipment.


It looks like green is the one for this job. Thanks.

OK so change mine to the green.
The blue should still work though, just may need to loosen the screw a bit,
apply the blue locktite, then tighten.

I've ordered the green from Amazon. I just arrived at the office to
find another pair of glasses with loose hinges. When it arrives, I'll
give it a test.

Good Lord, man! IT DOESN'T MATTER. It's a teeny, tiny screw. ANY OF THE THREE
will work just fine.

Good Lord, man! IF THIS ANNOYS YOU, DON'T READ IT. This particular
project doesn't amount to a hill of beans. But I have LEARNED A LOT
ABOUT THE DIFFERENCES BETWEEN LOCTITE PRODUCT, which may be useful on
other projects. Does your usenet reader allow you to ignore threads?

I have several of Magnivision Titanium reading glasses. They are by
far the best I've tried, and I've tried just about every brand there
is.

http://www.magnivision.com/collection.cfm?catid=8

There is just one little problem. The nose piece and the side pieces
are attached to the lenses with tiny bolts with a tiny nut on the
inside. Over time (few months), these work loose. If I catch them soon
enough, I can tighten them and they will stay put for another few
months. If I am too slow, the glasses fall apart.

The ones for the nose piece are much more likely to loosen, probably
because they get wiggled more.

I have tried superglue, but it really doesn't hold.

Can anyone recommend a way to secure these nuts? If it is permament,
so much the better. I don't know why they don't use rivets. I will
never want to loosen these nuts.


Take them where you bought them. They may prefer some way, i.e. Loctite,
SuperGlue, clear nail polish. There may be some reason that one of the
things suggested here might not work well, like discoloring the metal,
eating up any plastic it touches, etc. Something that one would not
normally think of, but in this application would be critical or detrimental
enough not to be a consideration. If it were just a nut and bolt, there
could be lots of suggestions that would probably work. Since this is a tiny
item, with unknown coatings, and unknown properties, if it were me, I'd take
it to where I bought it. They may even have a tube of GlassGoo or something
that is made specifically for that.

BTW, I have three pairs of titanium glasses, and there's nothing better.
But I do have to watch those little screws.

They look like the three pair I have. If his source was like mine,
a drugstore, the staff likely won't be of much help. Green Loctite
did the job for me. Just a tiny bit applied with a broomstraw to the
threads emerging from the nuts. Don't overdo it.

You think I'll get more than a blank stare at Long's Drug Store?
